Abstract
ABSTRACT Introduction and purpose We report a case of extensively drug-resistant (XDR) Pseudomonas aeruginosa (PA) scleritis after pterygium surgery. Methods Case report. Results A 58-year-old farmer presented with a 40-day history of severe pain, swelling, and blurred vision after a pterygium excision was performed at another institute. The patient was on multiple medications with no relief. The examination showed a nasally located scleral thinning in his right eye, with ulceration and infiltrates. Microbiology revealed Pseudomonas aeruginosa, which showed intermediate sensitivity to colistin only. The patient was administered topical (0.19%) and intravenous colistin and dexamethasone. There was a rapid reduction in symptoms, and the lesions healed over the next 2 months. Conclusions To the best of our knowledge, this is the first case report of XDR-PA scleritis. We suggest the possibility of evolving drug resistance caused by the iatrogenic use of antibiotics during the early stages of the disease course.
